Brake Squeal

The brake was fine with Brembo and EBC pads. I can't help wondering if it is something to do with the backing material.

Got to be worth cleaning the Discs and Pads with a proper brake cleaner just in case they have got contaminated

Ok. I will give it a real good clean with brake cleaner and see if it improves.

Did you clean and grease the pistons as crud builds up and if one seazes the pad will vibrate

The squeal can sometimes come from the interface between the side/edge of the back of the pad and caliper, so it can help to have a little dab of copper grease there. Cleaning will always help because it is dust/dirt between the surfaces that normally squeals, but cleaning only works until the dust builds up again.

One other thing that can sometimes cause a squeal is the leading edge of the pad where it touches the disc. Sometimes if that leading edge is very square it causes a squeal, which can be solved by filing an angle onto the leading edge.
